Proxy services for the secure upload of file system tree structures

ABSTRACT

The disclosure is directed towards proxy services for the secure uploading of file-system tree structures. A method includes receiving, at a web security service, an indication that client device to upload content to a storage cloud provider. The proxy service performs a security scan of the content while the content is stored on the client device. A security and/or a privacy concern is identified in the content stored on the client device. A security and/or privacy mitigation action is performed in response to identifying the security and/or privacy concern.

BACKGROUND

Many file systems structure or organize files within hierarchical tree and/or sub-tree structures. The root node of a tree (or sub-tree) structure is often referred to as a root-directory and the sub-nodes of the root-directory may be referred to as sub-directories. That is, each node of a tree corresponds to a directory (or a sub-directory of the root directory). One or more files may be associated with each node in the tree or sub-tree. When a file is associated with a node, the file is said to be located within the directory (or sub-directory) that corresponds to the node. This tree of directories may be a convenient “virtual” model of the file system's actual or physical structure. The details of the actual structure of most file systems may be significantly more complicated, where data associated with each file may be distributed across a plurality of data blocks. The data blocks for any given file may be distributed across non-consecutive regions of a magnetic or solid-state storage disk. That is, data for files may be physically segmented.

Nevertheless, ever since the early days of the internet, web browsers have enabled users to “upload” a file to a web service, via the user employing a user interface (UI) of the browser to select a file (located within a directory of their file system). Modern web browsers have advanced to the point where a user may upload an entire tree or sub-tree structure of directories (including all the files located within the root directory and all of the files located in each of the root-directory's sub-folders) via one or more selection mechanisms (e.g., a “drag and drop” mechanism). Being enabled to upload such hierarchical structures of directories/files presents numerous security issues for both the uploading system and a system that receives the uploaded directory tree.

SUMMARY

Various aspects of the technology described herein are generally directed to systems, methods, and computer storage media, for among other things, employing proxy services for the secure uploading of file-system tree structures. One exemplary, but non-limiting, method may include receiving, at a proxy service, an indication that a client device is to upload content to a storage cloud provider. Through the proxy service, a security scan of the content may be performed. In some embodiments, the content is scanned while the content is stored on the client device. In other embodiments, the content may be provided to the proxy service, and scanned at the proxy service. A security and/or a privacy concern may be identified within the content on the client device. A security and/or privacy mitigation action may be taken in response to identifying the security and/or privacy concern.

In some embodiments, the security and/or privacy scan includes scanning the content and additional content that is stored in a storage bin (e.g., a file-system tree structure) with the content. The storage bin may be a tree structure that includes a hierarchy of one or more file folders (e.g., file directories and/or sub-directories). In some embodiments, the security and/or privacy concern may not be in the content. For example, the security and/or privacy concern may be in the additional content.

In at least one embodiment, the method further includes communicating the request to the storage cloud provider. A storage cloud provider's website code for a content selection interface may be received. A security service code may be injected into the storage cloud provider's website code, by the proxy service, to create security-injected website code. The security-injected website code may be communicated to the client device. In some embodiments, the security and/or privacy mitigation action may include preventing the content from being uploaded to the storage cloud provider. In other embodiments, the security and/or privacy mitigation action may include providing an indication to the storage cloud provider that the client device poses a security threat.

Some embodiments include a system that includes at least one hardware processor and one or more computer-readable media having executable instructions embodied thereon. When the instructions are executed by the at least one hardware processor, the at least one hardware processor may perform operations that are included in one or more methods. At least one method includes transmitting, from a client device, a request addressed to a storage cloud provider. A security-injected client code for a storage cloud provider's interface may be received at the client device. The security-injected client code may be received from a proxy service. The storage cloud provider's interface may be provided for display (e.g., at the client device). A selection designating a content for upload to the storage cloud provider may be received (e.g., at the client device), through the interface. A security and/or privacy-related mitigation message may be received (e.g., at the client device) from the proxy service.

In some embodiments, the security and/or privacy mitigation message indicates that a security and/or a privacy concern was found in a file folder in which the content is stored. The security and/or privacy concern may not be in the content. The method may further include uploading the content to the storage cloud provider. The method may further include the security-injected client code performing a security scan of the content. The method may further include the security-injected client code performing a security scan of a storage bin in which the content is stored. The security-injected client code may be wrapped.

Some embodiments include computer storage media storing computer-useable instructions. When the instructions are used by at least one computing device, cause the at least one computing device to perform one or more methods. One such example (and non-limiting) method includes injecting, by a proxy service, a security service code into a storage cloud provider's client interface code to create a security-injected client code. The security-injected client code may be communicated to a client device. A request from the client device may be received at the client device. The request may be a request to upload one or more files to a storage cloud provider. A security scan of the content may be performed through the proxy service. The scan may be performed while the content is stored on the client device. In other embodiments, the scan may be performed at the proxy service (e.g., the content may be provided to the security service). A security and/or privacy-based rule violation may be identified and/or detected in content on the client device (or at the proxy service). A security and/or privacy mitigation action may be taken in response to identifying the security concern.

In some embodiments, the security scan may be performed through the security-injected client code. The security scan may include scanning the file and additional content that is stored in a folder with the file. The additional content may be in subfolders within the folder. The security and/or privacy rule violation may be information in the file that violates a privacy policy. The security and/or privacy mitigation action may include preventing the content from being uploaded to the storage cloud provider.

DETAILED DESCRIPTION Overview of Technical Problems, Technical Solutions, and Technological Improvements

As used herein, the term “set” may be employed to refer to an ordered (i.e., sequential) or an unordered (i.e., non-sequential) collection of objects (or elements), such as but not limited to machines (e.g., computer devices), physical and/or logical addresses, graph nodes, graph edges, and the like. A set may include N elements, where N is any non-negative integer. That is, a set may include 0, 1, 2, 3, . . . N objects and/or elements, where N is a positive integer with no upper bound. Therefore, as used herein, a set may be a null set (i.e., an empty set), that includes no elements (e.g., N=0 for the null set). A set may include only a single element. In other embodiments, a set may include a number of elements that is significantly greater than one, two, three, or billions of elements. A set may be an infinite set or a finite set. In some embodiments, “a set of objects” that is not a null set of the objects may be interchangeably referred to as either “one or more objects” or “at least one object.” A set of objects that includes at least two of the objects may be referred to as “a plurality of objects.”

As used herein, the term “subset,” is a set that is included in another set. A subset may be, but is not required to be, a proper or strict subset of the other set that the subset is included within. That is, if set B is a subset of set A, then in some embodiments, set B is a proper or strict subset of set A. In other embodiments, set B is a subset of set A, but not a proper or a strict subset of set A. For example, set A and set B may be equal sets, and set B may be referred to as a subset of set A. In such embodiments, set A may also be referred to as a subset of set B. Two sets may be disjoint sets if the intersection between the two sets is the null set.

The various embodiments are directed to employing a proxy session to secure the uploading of a file system's tree structure or a sub-tree structure of a file system. Because a sub-tree structure is inherently a tree structure, as used throughout, a sub-tree structure may be referred to as a tree-structure. Each node in a tree may correspond to a directory and/or a sub-directory. Each directory and/or subdirectory may include one or more data files. Some directories need not include a file and/or a sub-directory. Accordingly, such tree structures may be hierarchical in nature and include a root directory logically located at the top of the tree's hierarchical structure. That is, the root directory corresponds to the tree's root node. Some tree structures may include one or more sub-directories logically positioned below the root directory in the tree's hierarchical structure. One or more of the sub-directories may include one or more other sub-directories logically positioned below the sub-directory in the hierarchical structure, resulting in a cascade of directories. The tree structure may terminate in one or more sub-directories (e.g., corresponding to leaf nodes of the tree). As used throughout, the terms “directory” and “folder” may be used interchangeably, as well as the terms “sub-directory” and “sub-folder.”

In the embodiments, a web security service may be deployed in the context of a user employing a web browser to upload a tree structure of data files. For instance, a user may employ a web browser to select a tree structure of their device's file system. The web security service may serve as a proxy service that scans at least portions of (if not the entirety of) the data logically located within the tree-structure. For example, each file stored within the hierarchy of directories and sub-directories of the tree-structure may be scanned for potential security threats and potentially sensitive information. If a potential security threat and/or potentially sensitive information is detected, one or more interventions may be employed. Such one or more interventions may include preventing the upload from occurring. Other interventions may include deleting sensitive information and/or insecure portions of the data (e.g., portions of code that may be viral in nature) from the data that is ultimately uploaded. In at least one embodiment, an alert may be provided to a user when a security-related or a sensitivity-related issue with the data to be uploaded is detected. In order to quarantine such issues, the scanning of the data logically located within the tree may be performed within a sandbox of the web browser.

In one non-limiting embodiment, a user may employ a web browser (e.g., a browser) to select a tree structure of a file system to which they have access. The selection of the tree structure may be with the intent to upload all data logically located in the tree structure (e.g., all directories, sub-directories, and files logically located within the directories and sub-directories) to a web server. Prior to initiating the uploading, the web security service (WSS) acting as a proxy service may scan all such data. In at least one embodiment, as a proxy service, the WSS may detect an intention to upload data to a target destination (e.g., a web server). For example, the WSS may intercept one or more upload-related data packets intended for the upload's target destination. In response, the WSS may at least temporarily pause the uploading of data, via one or more application programming interface (API) function calls to the browser. The WSS may gain access to at least a portion of the file system that includes the tree-structure. For instance, when a user selects the tree-structure via their browser, the browser may have access to at least that portion of the file system. The WSS may gain access to that portion via one or more API calls to the web browser. The WSS may scan the associated data within a sandbox of the web browser. If no security and/or sensitivity issues are detected within the scanned data, the WSS may resume the upload to the target destination via one or more API calls. If one or more security issues are detected, the WSS may perform one or more interventions through one or more API calls. For example, the WSS may terminate the upload process, delete portions of data associated with the detected issues from the upload process, and/or provide the user (and/or the target destination) with one or more warnings and/or alerts.

In other embodiments, the scanning of the data may be performed at the WSS. For example, again as a proxy service, the WSS may intercept the uploading of the tree structure (and its data). The WSS may scan the data one or more devices that implement the WSS (e.g., server devices remote from the user's client device). For example, the WSS may implement a sandbox at its implementing server device. The data may be scanned within such a sandbox. If no issues are flagged during the scanning, the WSS may relay the uploaded content to the target destination (e.g., the intended web server). If one or more issues are detected within the uploaded data, then the WSS may perform one or more interventions.

Overview of Environments for the Secure Upload of File-System Tree Structures

Aspects of the technical solution can be described by way of examples and with reference to FIG. 1 and additional illustrations below. FIG. 1 illustrates a block diagram showing an example operating environment 100 in which some embodiments of the present disclosure may be employed. It should be understood that this and other arrangements described herein are set forth only as examples. Other arrangements and elements (e.g., machines, interfaces, functions, orders, and groupings of functions) can be used in addition to or instead of those shown, and some elements may be omitted altogether for the sake of clarity. Further, many of the elements described herein are functional entities that may be implemented as discrete or distributed components or in conjunction with other components, and in any suitable combination and location. Various functions described herein as being performed by an entity may be carried out by hardware, firmware, and/or software. For instance, some functions may be carried out by a processor executing instructions stored in memory.

Among other components not shown, example operating environment 100 includes a number of user devices, such as user devices 102 a and 102 b through 102 n; a number of data sources, such as data sources 104 a and 104 b through 104 n; server 106; sensors 103 a and 107; and communication network 110. It should be understood that environment 100 shown in FIG. 1 is an example of one suitable operating environment. Each of the components shown in FIG. 1 may be implemented via any type of computing device, such as computing device 700 described in connection to FIG. 7 , for example. These components may communicate with each other via network 110, which may include, without limitation, a local area network (LAN) and/or a wide area networks (WAN). In exemplary implementations, network 110 comprises the Internet and/or a cellular network, amongst any of a variety of possible public and/or private networks.

It should be understood that any number of user devices, servers, and data sources may be employed within operating environment 100 within the scope of the present disclosure. Each may comprise a single device or multiple devices cooperating in a distributed environment. For instance, server 106 may be provided via multiple devices arranged in a distributed environment that collectively provide the functionality described herein. Additionally, other components not shown may also be included within the distributed environment.

User devices 102 a and 102 b through 102 n can be client devices on the client-side of operating environment 100, while server 106 can be on the server-side of operating environment 100. Server 106 can comprise server-side software designed to work in conjunction with client-side software on user devices 102 a and 102 b through 102 n to implement any combination of the features and functionalities discussed in the present disclosure. This division of operating environment 100 is provided to illustrate one example of a suitable environment, and there is no requirement for each implementation that any combination of server 106 and user devices 102 a and 102 b through 102 n remain as separate entities.

User devices 102 a and 102 b through 102 n may comprise any type of computing device capable of use by a user. For example, in one embodiment, user devices 102 a through 102 n may be the type of computing device described in relation to FIG. 8 herein. By way of example and not limitation, a user device may be embodied as a personal computer (PC), a laptop computer, a mobile or mobile device, a smartphone, a tablet computer, a smart watch, a wearable computer, a personal digital assistant (PDA), a music player or an MP3 player, a global positioning system (GPS) or device, a video player, a handheld communications device, a gaming device or system, an entertainment system, a vehicle computer system, an embedded system controller, a camera, a remote control, a bar code scanner, a computerized measuring device, an appliance, a consumer electronic device, a workstation, or any combination of these delineated devices, or any other suitable computer device.

Data sources 104 a and 104 b through 104 n may be discrete from user devices 102 a and 102 b through 102 n and server 106 or may be incorporated and/or integrated into at least one of those components. In one embodiment, of data sources 104 a through 104 n comprise sensors 103 a, 107, which may be integrated into or associated with the user device(s) 102 a, 102 b, or 102 n or server 106. Examples of sensed user data made available by data sources 104 a through 104 n may include events.

Operating environment 100 can be utilized to implement a component of the components of an enhanced web security system 200, described in FIG. 2 , including components for proxy services for the secure upload of file-system tree structures. Operating environment 100 also can be utilized for implementing aspects of process flows 300-600 described in conjunction with FIGS. 3-6 .

Overview of Example of Proxy Services for the Secure Upload of File-System Tree Structures

FIG. 2 illustrates a block diagram showing an example web security system 200 in which some embodiments of the present disclosure may be employed. System 200 may be implemented via one or more components of environment 100 of FIG. 1 . System 200 may include web security service (WSS) 240 implemented by one or more computing devices (e.g., web security server computing device 202). System 200 may additionally include a client computing device 206 and a web-server computing device 204. In some non-limiting embodiments, system 200 may include a client proxy server 208. The web security server computing device 202, the web-server computing device 204, the client computing device 206, and/or the client proxy server 208 may be communicatively coupled via communication network 110 of FIG. 1 .

The web-server computing device 204 may host or otherwise implement a web application (e.g., a cloud-computing application, a web page, and/or a web application). The WSS 240 may provide web (or cloud) security proxy services to the client computing device 206. In embodiments where the application is a cloud application, rather than a web application, the web security server computing device 202 may be a cloud security server computing device and the WSS may be a cloud security service. Whether the application is a web-based application or a cloud-based, the WSS 240 may provide security services for the secure upload of file-system tree structures, from the client computing device 206 to the web-server computing device 204.

The client computing device 206 may have access to a file system 220. In some embodiments, the file system 220 is implemented locally on client computing device 206. For example, the file system may manage content stored on a storage device that is local to the client computing device 206. In other embodiments, the file system 220 is remote to the client computing device 206. For instance, the file system 220 may be implemented by another computer device, and the file system 220 manages content stored on a storage device that is remote to the client computing device 206, e.g., a remotely mounted storage device. The file system 220 may include and/or manage a hierarchical tree structure 222. The tree structure 222 may include a hierarchy (e.g., a tree) of cascading file directories and filed sub-directories, e.g., folders and sub-folders. One of more of the directories and/or sub-directories may include one or more files. Thus, the tree structure 222 may include a hierarchical set of files. The files may encode content (e.g., data and/or information).

To interact with a cloud-based application, a web-based application, and/or a web page implemented by web-server computing device 204, a user may employ the client computing device 206. More specifically, the user may employ web browser 210 implemented by the client computing device 206 (or another device that client computing device may access via communication network 110) to interact with any application or web page implemented by web-server computing device 204. In some embodiments, the web browser 210 may include an uploader agent 212. The uploader agent 212 may enable the user to select at least a portion of the tree structure 222 to upload to the web-server computing device. As shown in FIG. 2 , the user has selected sub-tree structure 224 to upload to web-server computing device 204. Uploader agent 212 is enabled to initiate and perform an upload session with the web-server computing device 204. The entirety of the contents of the sub-tree structure 224 may be uploaded to the web-server computing device 204 in the upload session. The uploaded contents may include all the directories, sub-directories, and files included in the sub-tree structure 224.

In the various embodiments, the WSS 240 may act as a proxy service to manage the upload session. The client proxy server 208 may at least enable the WSS 240 to act as a proxy service to the client computing device 206.

The WSS may include a network module 242 to communicate with each of client proxy server 208, client computing device 206, and web-server computing device 204. The WSS 240 may additionally include a data security scanner (DSS) 244. The DSS 244 is generally responsible for scanning the contents (e.g., data and/or information) being uploaded from client computing device 206 to web-server computing device 204. More specifically, the WSS 240 may be deployed in the context of the user employing the web browser 210 to upload the sub-tree structure that includes a plurality of directories and data files. The WSS 240 acts as a proxy service that scans at least portions of (if not the entirety of) the data logically located within the sub-tree structure 224. For example, each file stored within the hierarchy of directories and sub-directories of the sub-tree structure 224 may be scanned for potential security threats and potentially sensitive information. If a potential security threat and/or potentially sensitive information is detected, one or more interventions may be employed. Such one or more interventions may include preventing the upload from occurring. Other interventions may include deleting sensitive information and/or insecure portions of the data (e.g., portions of code that may be viral in nature) from the data that is ultimately uploaded. In at least one embodiment, an alert may be provided to a user when a security-related or a sensitivity-related issue with the data to be uploaded is detected. In order to quarantine such issues, the scanning of the data logically located within the sub-tree structure 224 may be performed within a sandbox of the web browser 210.

As noted above, a user may employ the operations of the uploader agent 212 to select the sub-tree 224 from the tree structure 222. The selection of the sub-tree structure 224 may be with the intents to upload all data logically located in the sub-tree structure 224 (e.g., all directories, sub-directories, and files logically located within the directories and sub-directories) to a web server. The WSS may receive an indication of an initiation of the upload session and then scan all such data prior to the data being uploaded to the web-server computing device 204. In at least one embodiment, as a proxy service, the WSS 240 may detect an intention to upload data to a target destination (e.g., a web server). For example, the WSS 240 may intercept one or more packets indicating an initiation of an upload session (e.g., with a target destination of the web-server computing device 204). In response, the WSS 240 may at least temporarily pause the uploading session, via one or more application programming interface (API) function calls to the browser 210. The WSS 240 may gain access to at least a portion of the file system 220 that includes the sub-tree structure 224. For instance, when a user selects the sub-tree structure 224 via browser 210, the uploader agent 212 may gain access to at least the portion of the file system 220 that includes the sub-tree structure 224. The DSS 244 may gain access to that portion of the file system 220 via one or more API call to the web browser 210. The DSS 244 may scan the associated data within a sandbox of the web browser 210. If no security and/or sensitivity issues are detected within the scanned data, the WSS 240 may resume the upload session and provide the sub-tree structure 224 (and its associated data) to the upload session's target destination (e.g., web-server computing device 204) via one or more API calls. If one or more security (or data sensitivity) issues are detected, the WSS 240 may perform one or more interventions through one or more API calls. For example, the WSS 240 may terminate the upload session, delete portions of data associated with the detected issues from the upload process, and/or provide the user (and/or the target destination) with one or more warnings and/or alerts.

In other embodiments, the scanning of the data may be performed at the WSS 240. For example, again as a proxy service, the WSS 240 may intercept the uploading of the sub-tree structure 224 (and its data). The DSS 244 may scan the data (at one or more devices that implement the WSS, e.g., the web security server computing device 202). For example, the DSS 244 may implement a sandbox at the web security server computing device 202. The data may be scanned within such a sandbox. If no issues are flagged during the scanning, the network module 242 may relay the uploaded content to the target destination (e.g., the web-server computing device 204). If one or more security and/or sensitivity issues are detected within the uploaded data, then the WSS 240 may perform one or more interventions.

Example Methods for the Secure Upload of File-System Tree Structures

FIGS. 3-6 provide flow diagrams that illustrate various methods (e.g., methods 300-600) for proxy services that secure the uploading of file-system tree structures. Any of methods 300-600 may be implemented and/or performed by using any of the embodiments of a web security service (WSS), such as but not limited to WSS 240 of FIG. 2 . In embodiments, one or more computer storage media having computer-executable instructions embodied thereon that, when executed, by one or more processors can cause the one or more processors to perform the methods in the storage system. Generally, the flow diagrams of FIGS. 3-6 can be implemented using the architectures described above at least in conjunction with FIGS. 1-2 . For example, any suitable combination of portions of methods 300-600 may be implemented by WSS 240.

Turning to FIG. 3 , FIG. 3 provides a flow diagram that illustrates a non-limiting method 300 for employing a proxy service to secure the uploading of a file-system tree structure, in accordance with the various embodiments. Initially, method 300 begins at block 302, where an indication (e.g., an upload indication) that a client initiated an upload session with a remote device is received at a web security service (e.g., WSS 240 of FIG. 2 ). The upload indication may include an indication of a file-system tree structure (e.g., sub-tree structure 224 of FIG. 2 ) that includes a hierarchical set of files encoding content (e.g., data and/or information). The files may include source code, content for documents, and the like. At block 304, in response to receiving the upload indication, the WSS may be employed to at least temporarily suspend the upload session. At block 306, the WSS may be employed to access the tree structure. For example, the WSS may issue an API call to a web browser employed by a user of the client to initiate the upload session. At block 308, the WSS may be employed to scan the content (accessed at block 306). For example, the DSS 244 of FIG. 2 may scan the data included in the entirety of the files stored in each of the directories/sub-directories included in the tree structure for security issues and/or sensitivity (e.g., data privacy) issues. In some embodiments, the data scan may be directed towards scanning the data to identify portions of the content that include data and/or information that may be correlated with one or more computer and/or network security issues. For example, the content may be scanned via one or more virus scanning methods. The scanning may also be directed towards identifying portions of the content that include sensitive information (e.g., data that may be subject to data privacy issues). In order to quarantine such security and/or privacy issues, the scanning may be performed within a security sandbox of the web browser.

At decision block 310, it is determined whether the data scan performed at block 308 has identified and/or detected any security and/or data sensitivity issues. If any such issues have been detected during the data scan, method 300 may flow to block 312. If no security and/or sensitivity/privacy issues are identified, the method 300 may flow to decision block 314. At block 312, in response to identifying one or more security and/or sensitivity issues, one or more interventions, directed at the identified issues, may be performed. Such one or more interventions may include preventing the upload from occurring. Other interventions may include deleting sensitive information and/or insecure portions of the data (e.g., portions of code that may be viral in nature) from the data that is ultimately uploaded. In at least one embodiment, an alert may be provided to a user when a security-related or a sensitivity-related issue with the data to be uploaded is detected. From block 312, method 300 may flow to decision block 314.

At decision block 314, it is determined whether the scanned content should be updated. If the scanned content is to be updated, method 300 may flow to block 316. If the scanned content is not be updated, then method 300 may flow to decision block 318. At block 316, the WSS may update the content to be upload. For example, the WSS may delete portions of the content. In at least some embodiments, the WSS may inject data into the content. For example, the WSS may inject executable code, privacy statements, alerts, warnings, or any of such information into the content to be uploaded. In at least one embodiment, anti-virus software may be injected into the content. Method 300 may flow to decision block 318.
